Managing the hedgerows here is one of the most important things for us to get right. Tall hedgerows with wide bases provide food and shelter for all sorts of wildlife as well as being essential corridors linking habitats. Hedges support up to 80% of our woodland birds, 50% of our mammals and 30% of our butterflies as well as much other invertebrate life.
But in order to stay as a hedge rather than growing up into trees, the occasional cut is required. Hawthorn and Blackthorn only flower on old wood, so if only a third of the hedgerow is cut each year, it will then be just this third that will not flower and produce fruit the next season. Butterfly Conservation, however, argue that hedges should be cut less often than that, and only then in the late winter, to allow the many invertebrates that overwinter on the wood to complete their life cycles.
We use a nearby and reliably good agricultural contractor and this week a large green and yellow John Deere tractor arrived in the meadows to trim back our hedges:

Although we have a kilometre of hedge here, only half of it is actively managed. The other half has not been cut for decades and is now so overgrown and ivy-clad that it can no longer be cut with a flail head on a tractor. This is an unhealthy state for any hedge to be in and bits have already started falling over, but it is still producing a lot of fruit as well as offering all manner of safe places for invertebrates to overwinter.

Five years ago we planted an 85m stretch of mixed native hedgerow and it has already started to bear fruit. I am still annually pruning this with secateurs to encourage it bush out.

The remaining half a kilometre of hedgerow is cut with a flail head every other year:

The flail head rotates at 3,000 rpm and the cut vegetation is munched up into tiny bits and effectively disappears as mulch into the hedgerow rather than needing to be cleared up.

It is always a slightly shocking sight to see it in the meadows.

The heavy tractor makes quite a mess of the soft January ground:

The hedgerow took six hours to cut this week. Although we do need to give the contractors enough work to justify the trip over here, perhaps the job could be divided into two, or maybe even three, sections in the future to be done on successive years. In this way we would be achieving the rotation recommended as best practice to manage the hedgerows for wildlife.
Dave and I are part of the Walmer Castle volunteer wildlife team, monitoring and recording the wildlife there, as well as helping with the wildlife walks of the grounds that are put on for visitors to the Castle.

These days the Castle is open to the public as well as being the official residence of the Lord Warden of the Cinque Ports. It is also a historic garden and the National Collection of Greatorex double snowdrops has its home there. Other snowdrop varieties are grown as well and some of these are already out in flower and being displayed in the kitchen garden for us to admire:

The snowdrops had even attracted a hoverfly in the weak January sunshine:

Last week we went down into one of the tunnels under the Castle to see what butterflies and moths might be hibernating there.

The tunnels circumnavigate the castle with regular gunports looking out across the bottom of the moat, which has always been dry:


We didn’t find any hibernating butterflies down there but we did find three species of moth. Only a very small minority (2%) of British moths hibernate as adults and the herald is one of few that does. Its larval foodplants are willows and poplars and there aren’t many of those trees around here, so it was nice to see two heralds in the Walmer Castle tunnel this week:

There were also three twenty-plume moths. The caterpillars of these moths feed on the leaves and buds of honeysuckle:

In March 2023 I found one of these moths in the house. The light from the alarm box shining through its wings showed what an odd structure they are:

I also found six Bloxworth snouts down in the tunnels. Until recently this was only a very rare immigrant to mainland Britain, but has became established along the south coast and now seems to be spreading inland. The moth got its common name from being first discovered on an outhouse door at Bloxworth rectory in Dorset in 1884:

There are two generations each year, the first flying in July and August, and the second in September and October. It is this second brood that will overwinter as adults in tunnels where the temperature is more stable. The larvae feed mostly on pellitory-of-the-wall, Parietaria judaica, which is a plant that grows plentifully amongst the Castle’s stonework.

A graph from the Kent Moth Group website shows sightings of the Bloxworth snout in Kent over time:

We also saw the egg sac of a cave spider, Meta menardi, dangling on a 5cm silken thread from the roof:

This crow has been named Russell (ie Russell Crowe) by the English Heritage staff at the drawbridge where it regularly hangs out on the battlements:

The kestrels are also still being seen most days in the trees flanking the Castle drive:

A family of sparrowhawks were raised in the Castle grounds last summer and we think we have found the large nest:

Back home, this rather ramshackle bowl of bulbs is what is left of the forced hyacinths, especially prepared so that they flowered at Christmas. They are well past their best and have now gone outside to die back before being planted out into the garden in the autumn:

In accordance with instructions, I planted the bulbs into the bowl in early September and left them outside until the beginning of December, at which point they came into the warmth of the house. During this sojourn outside, though, a jay must have buried a walnut in there and this started to grow as soon as the bowl was brought inside.
It was a bumper year for our neighbours’ walnut tree and we saw both crows and magpies making the most of the bonanza:


We only saw jays with acorns, however:

But it is only the jays that will bury nuts away in the soil to feed themselves through the winter.
I extracted the fledgling walnut tree from the pot of hyacinths….

…and put it in its own deep pot to plant out once it has matured a bit more.
There has been a lot of tawny owl activity in the meadows of late. One night this one was on a perch…

…and this photo was taken shortly afterwards. What is going on?

The obvious explanation is that the bird was defecating – but surely that would have been a fast expulsion and so why isn’t it blurry? This remains a bit of a question mark for me.
It is fox mating season, when the males start shadowing the vixens to claim them for themselves and I am seeing pairs of foxes on cameras throughout the meadows. In the photo below, there is also a very brightly lit ship out to sea in the top right hand corner:

It is The Patricia, who anchored alongside us one night this week. Operated by Trinity House, she maintains the buoys and lightship that guard the notorious Goodwin Sands just offshore from the meadows. I have covered the Goodwin Sands in more detail in this previous post: https://walmermeadows.co.uk/2024/05/12/walking-on-the-goodwins/

We last saw her back in November working on the Mew Stone buoys in South Devon when we were on holiday there. Now happily on the other side of midwinter, it feels very right that we are both safely back in Kent.
